I worked out a design last year, but then got lazy about getting some made after I discovered the supply of B21 chips dried up. I'll still probably make some "for science," but if anyone else wants them, it will be a bring-your-own-B21 board that you have to complete yourself.

Not sure what's in the works for the upcoming multi, if C board is modelled in an FPGA, these solutions might be obsolete.
 
Ok @lydz, how do you use this? What are the hex files for? What are the dip settings for each game.
 
Would be great to have a C board you could easily/quickly change which version it is, ie. B-17, B-4, etc. . .

Ok, we made a little progress. But that doesn't tell anyone what game maps to the code in column A. Can you update the spreadsheet to add in the game?

Also, what are we supposed to do with the hex files? Surely, you cannot burn a hex file to a PAL? You need a JED file for a PAL, correct?
